To all whom it may concern:

Be it known that 1, DAVID L. ELLIS, a citizen of the .United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Ventilating Apparatus, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

My invention relates to improvements in ventilating appliances for theventilation of water closet bowls, urinals and like devices in which'foul odors are me ated or produced, though it is not limited to use with such devices, butmay be used for the ventilation of bath rooms, kitchens or other rooms which it is desired to ventilate.

The invention relates particularly to the class of ventilating devices in which a jet or spray' of water dis charged under pressure in a chamber or tube induces a current of air in the direction of the discharge, drawing in or exhausting fromthe closet bowl or other vessel,

- or room, to which the device may be connected, the

foul odors or gases which are to be disposed of, and it is the object of the invention to produce a simple. and inexpensive device for this purpose which will be capable in operation of securing an effective exhaustion of the foul odors or gases with the least expenditure of water, which will be quickly freed of the water used .and in which all the operating parts will be carried by a. single casting and will be so arranged that they may be readily gotten at for cleaning or repair without disturbing the device as a whole.

A further object of the invention is to so construct the device that it may be readily attached to any of the forms of closet bowls in use without change in construction so that it may be carried in stock by plumbers and connected up, whatever construction of bowl may be used, without the necessity for special forms for dif-, ferent bowls.

A further object of the invention is to provide means for controlling the Water supply by the pressure of the closet seat which will be simple, positive and not liable to get out of order or need attention.

A further object of the invention is to provide in connection with the ventilating device, as applied to closet bowls, improved means for holding up the seat when not in use, so that waste of water is prevented,

and means by which the seat is guided and held firmly in place when depressed and in ury to the bowl, if carelessly slammed down,'is prevente With these and other objects, hereinafter explained,

.in view, my invention consists in the construction and combination of elements hereinafter set forth and particularly pointed out in the claims.

Referring to the drawingsFigure l. is a side elevation of an ordinary closet bowl, sh owing my ventilating bowl shown having its local vent on the left.

Figs. 10, 10, 1-1, 11*}, l2, 12, 13 and 14 are detail sec tional views, showing modified forms of the spraying plug. Fig. 15 is a sectional view showing the ventilating device applied to a battery of urinals. Figs. 16 and 17 are views in front and side elevation showing the arrangement of the device as applied to urinals.

In .the drawings, 1 is the spray chamber of my ventilating device, shown in Figs. 1, 2 and 3, connected at its intake end with the closet bowl 2.

3 is the discharge end of the spraying chamber connected by an elbow and ordinary piping with the vent pipe 4. The construction of the spray chamber will be hereinafter described in detail.

5 is the water controlling device or valve operated by'the closet seat 6.

7 isthe spring secured to the under side of the seat for holding the seat in raised position out of operative. contact with the valve and 8 is the bumper, also se- Fig. 3

cured to the under side of the seat to iorma cushion for the bowl when the seat is forced down.

9 is the flush tank shown in Fig. 1 arranged as is common in closets of the low down type.

10 is the flush pipe leading from the flush tank to the bowl; -ll is a fitting secured to the vent pipe 4, connected by pipe 26 with the spray chamber 1; 12 is the locahvent connection of the closet bowl 2. To this local vent connection, the intake end of the spray chamber is connected by ring 13, screw threaded on the end of the spray chamber and corrugated on the interior of the portion fitting over the local vent 12, to

- which it is cemented by plaster of paris 14. The end of the-spray chamber on which the ring 13 fits has its center below the vertical center of the spray chamber, so that the lowest point of opening in it is on a line with the'bottomof the spray ch amber and thus water discharged into the spray chamber will flow freely into is at no point of lesser area than the area of the local ventand be discharged into the bowl. In different constructions of closet bowls the local vent differs somewhat in size and shape and it will therefore be necessary to provide rings differing somewhat in the shape and size of the portion which fits over the local vent, but the screw connection should be made standard, so that no change in the spray chamber need be made to fit dilierent bowls.

The spray chamber 1 comprises an enlarged sec shown at 42 into which leads an inlet conduit 43, the area of which is considerably less than the area of the enlarged section 42.- The walls of the inlet conduit merge into the walls of the enlarged section, the two beingiormcd in one piece, by way of a substantially vertical connecting wall; and through this connecting wall posses the devices hereinafter disclosed for discharging a jetv of water in the form oi sprny lon itudb nally oi the spray chamber as shown in Fig. it will be seen that this construction results in a spin into, and that the passage through which the or opening.

In constructions in which a bowl not lm'vi vent is used, the intake end of the spray chem may be connected directly to the lush pipe by means of the connection shown in Figs. 6 and 7. In this arrangementa special fitting 15 is used having a flap valve 16 so arranged that it will be closed by the water when the flushing is goingon so as to prevent water from entering the discharge end of the spray chamber. In this arrangement, it will be understood that the ventilating device draws the foul odors or gases from the bowlthrough the same openings through which the flush water enters and, of course, while the flushing is going on the ventilating device cannot operate to draw off the gases; This is'not of importance, however, as the gases will have been removed before the flushing takes place.

This modification will be used in case the ventilating device is to be attached to bowls already installed which are not provided with local vents. Where new worlc is to be installed, it will be preferable to use bowls having local vents and to connect the ventilating device with the local vent asshown in Figs. 1 and 2.

The water controlling valve 5 is connected by pipe 17 with the water supply pipe and is connected by pipe 19 with the spud 21 on top 0} the spray chamber the pipes 17 and 19 forming a supply conduit through which water is supplied to the spray chamber 1. pipe 19 serves to support the valve in position to have its projecting stem 18 pressed downward to open the valve by the depression of the seat 6. The valve 5 is of any usual construction having the valve below its valv seat so that it will be normally held closed by the water pressure. The stem 18 is surrounded with a stufiing box of usual construction to prevent leakage.

The wall of the spray chamber 1 that connects the chamber 41 and said offset is provided with a spud 21 The sooner aontally as shown at 2l1 in Fig. 4' from a. hiddified opening in the walls of the water chamber. The

plug may be arranged to project into thespray chamber in a direction longitudinal oithe spmy chamber at a s shown Fig. 3, or the arrangement may be slightly module-:1 and have the form illustmted in Fig. 4. In either e, the discharge orifice or nozzle 23 oi the .ug is so arranged as to throw the spray chamber, and to distribute the spray in to completely fill. the discharge end iber with sprsy. ttom line of the spray chamber is inclined h end and the spray chamber is pro: poriion'into whiclrtbe spray is discharged diaphragm near the bottom. The spray cham is also preferably provided near the discharge end with. of inclined plates or deflectors 25 int collecting'the water of the spi e-y. 'lhese plates are ior the purpose of separating the water from the gases. 'They are arranged a position slightly inclined from the horizontal and sloping slightly toward the discharge end of the spray chamber, so that water collected by them will readily run off. The arrangement or the plates disclosed pibduces an effective separating device and one that offers minimum. obstruction to the gases as they flow through the spray chamber. I

26 is an elbow leading from the opening. in the top of the discharge end of the spray chamber, to which the piping leading to the vent pipe is connected.

The spring 7 shown in detail in Figs. 8, Wand 3 is secured to the under side of the seat by screws 27,

t inclination to the axis of the chamber as i passage 24 for water formed by s hori--' lir lly of and towards the discharge end of passing through coils 7, formed at the ends of the v springs. The spring is of a single piece of wire coiled at 7 to form springs, the portion between the coils 7 being bent to form a bail 7 adapted to bear against the upper edge of the bowls. I

The bumper 8 shown in detail in Figs. 9,9, and 9, consists of a plate attached to the under side of the seut having a central opening in which a suitably shaped piece of rubber is firmly held.

Figs. 10 to 14 inclusive show modified forms oi pin and nozzle for discharging water into the spray chamber. In Fig. 10 the spraying plug. 221 is shown as pro-. vided with two passages 30, and said plug is provided with a nipple 32 upon Whichis a cap 31 having a. centrsl tapered discharge orifice, in which orifice a deflecting spindle 33 is located. This spindle may be removable as shown at 331 Fig. 10. The spindle in either case is of such diameter relative to the discharge orifice in the cap 31 that an annular space is provided for the discharge of the water and the form of the spindle and orifice is such that the stream of water discharged is'oi conical form. i

In the form shown in Fig. 11, the plug 222'is procateQone or .a plurality of passages through which the" water passes, as indicated in Figs. 12 and 12 respectively. I

In the construction shown in Figs. 3 and 13, the discharge nozzle or orifice 23 is shown as formed in a piece removable from the spraying plug, and is constricted midway oiits length. i f In the form shown in Figs. 4 and 14 the plug 224 is shown as provided with a removable tip 313 having a laterally opening orifice communicating with the Water supply passage 303 within the spraying plug.

15, 16 and 17 show a sectional view of the apparatus applied to a battery of urinals in a inodified form flushing tank 36 used to flush the urinals intermittently.

'22 is the spray plug; 19 is the water connection have ing a water supply pipe leading thereto. 7

. 37 is the main suction pipe leading out to the different urinals which can be made ofanyregular piping or tubing with fittings for the connection of the various individual intake pipes 38. On the'lower end of each intake pipe, 38,'a suitably shaped hood is attached directly over the-urinal bowls to better facilitate the collecting of the odors. These hoods 39 will necessarily be made in different forms and shapes to fit the different styles and shapes ofnrinals. In 5 me cases hoods are made a part of the urinal bowl i' which caseth pipes 38 will be attached directly thereto.

The operation of the ventilating device will be readily understood from the above description. Briefly stated, the ,operation' is as follows: On the depression of the seat 6 by the weight of -the person using the closet, the valve stem 18 will be forced downward against the pressure of the water opening the valve and permitting water to flow tothe water chamber 41 from which it passes to the spraying plug 22 and is discharged through the nozzle 23 in the form of spray toward the discharge end of the spraying chamber creating an air current towards the vent pipe and drawing in air -through the local vent from the interior of'the bowl,

the air so drawn in carrying with it any foul odors or gases present in the bowl. The spray condenses in the deflector plates 25 and the Water drips downward and flows through the return passage 24 back to the bowl. When the seat is freed from pressure, it is immediately raised by the spring 7 relieving the valve stem 18 from pressure whereupon the valve is at once closed by the water pressure.

It will be noted that by the arrangement of the spraying plug in an offset or shoulder, an' unobstructed passage for the entrance of the gases from the bowl is afforded. By so constructing the nozzle 23 that the spray is distributed over the entire cross sectional area of the chamber, a strong draft is created with the use of very little water. I have found that in the use of my device, 5 cubic feet of air will be drawn in for each gallon of water.

The spraying plug being distinct from the water controlling valve and being so arranged as to be readily accessible without disturbing the connections of the spraying chamber, may be readily withdrawn for cleaning or repair.

It will, of course, beunderstood that I} do not desireto be limted to the precise form or arrangement of parts shown in the drawings as it Will be obvious that both form and arrangement may be varied without departing from the spirit of the invention.
